"Lordstown's trucks were the canvas for Elaphe Propulsion Technologies, a Slovenian company developing in-wheel electric motors that can deliver and adjust torque at each wheel completely independently. Electric motorspaired with their invertersconvert the energy from the battery pack into rotational kinetic energy at the wheels. Most modern EV motors are already torque-rich and operate efficiently across a wide RPM range, but their architecture still leaves performance and packaging potential untapped."
"In-wheel motors (or hub motors) aren't a new concept. Ferdinand Porsche's earliest electric cars produced over a century ago used them. But in the modern era, almost every automaker has defaulted to a transaxle motor, where torque travels through a single-speed gearbox, CV joints, and half-shafts before reaching the tires. That's true even in most quad-motor designs. These setups are compact compared to internal combustion drivetrains, but traditional engines are a pretty low bar."
Two Lordstown Endurance electric pickups served as platforms for Elaphe Propulsion Technologies' demonstration of in-wheel motor technology near Ceplje, Slovenia. Elaphe develops hub-mounted electric motors that deliver and adjust torque independently at each wheel. Electric motors combined with inverters convert battery energy into rotational kinetic energy at the wheels. While modern EV motors are torque-rich and efficient across wide RPM ranges, conventional transaxle architectures still use single-speed gearboxes, CV joints, and half-shafts. Integrating motors into the wheel hub bypasses these components, improving packaging and unlocking additional performance potential. In-wheel motor concepts date back to Ferdinand Porsche's early electric cars.
